Hyperoxemia Education to Nurses to Increase the Adherence to Oxygen Weaning Goals in Inpatient COPD Patients.

Hyperoxemia in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) are at risk for increased hospital stay, mechanical ventilation, and increased risk of death. Literature supports that establishing increased education to nursing staff on the risks of hypoxemia to increase adherence to oxygen weaning protocols has the potential to improve future practice. Oxygen weaning protocols are often not followed for concern of patient care. Nurses may believe to be helping patients when increasing oxygen, when they could actually be potentially harming them. Increased education on hypoxemia in COPD patients for the nursing staff will assist them to feeling more comfortable following oxygen weaning goals to achieve ordered O2 saturation for their patients. This DNP project focused on evidence based data for hyperoxemia in AECOPD patients with education for nurses to enhance their knowledge. The nurses were presented with an educational poster presentation and a post test to evaluate their hyperoxemia knowledge in AECOPD patients. The educational goal for improvement was to have the nurses to score 80% or higher on the post test. This goal was achieved, implying it was a successful strategy for improvement of knowledge. For future projects in this topic, it would be beneficial to have include a pre and post chart audit to evaluate if the education is being implemented into nursing practice

Cooperative Learning At A Distance: An Experiment With Wikis

The merits of incorporating group work into learning environments are well established.  Online classes and other distance learning settings, however, can make it challenging to introduce traditional group projects.  Wikis use technology to facilitate group work in distance learning settings.  Wikis allow individuals in different locations to asynchronously post and edit content on a website to iteratively and cooperatively work toward a solution.  We describe wikis and their use in an online MBA managerial accounting class.  Student feedback on their experiences using wikis as well as instructor observations were mostly positive while negative comments were primarily administrative in nature and easily addressed.  In general wikis can be implemented in any business course using group assignments.  When using wikis for cooperative learning, the obstacles are minimal, but the potential benefits for students may be substantial.  These benefits include developing a sense of community, participating in peer-to-peer learning and using critical thinking and communication skills while still enjoying the convenience of working asynchronously in disparate locations

The inevitable youthfulness of known high-redshift radio galaxies

Radio galaxies can be seen out to very high redshifts, where in principle they can serve as probes of the early evolution of the Universe. Here we show that for any model of radio-galaxy evolution in which the luminosity decreases with time after an initial rapid increase (that is, essentially all reasonable models), all observable high-redshift radio-galaxies must be seen when the lobes are less than 10^7 years old. This means that high-redshift radio galaxies can be used as a high-time-resolution probe of evolution in the early Universe. Moreover, this result helps to explain many observed trends of radio-galaxy properties with redshift [(i) the `alignment effect' of optical emission along radio-jet axes, (ii) the increased distortion in radio structure, (iii) the decrease in physical sizes, (iv) the increase in radio depolarisation, and (v) the increase in dust emission] without needing to invoke explanations based on cosmology or strong evolution of the surrounding intergalactic medium with cosmic time, thereby avoiding conflict with current theories of structure formation.Comment: To appear in Nature. 4 pages, 2 colour figures available on request.

Safety and efficacy of VB-111, an anticancer gene therapy, in patients with recurrent glioblastoma: results of a phase I/II study.

BackgroundVB-111 is a non-replicating adenovirus carrying a Fas-chimera transgene, leading to targeted apoptosis of tumor vascular endothelium and induction of a tumor-specific immune response. This phase I/II study evaluated the safety, tolerability, and efficacy of VB-111 with and without bevacizumab in recurrent glioblastoma (rGBM).MethodsPatients with rGBM (n = 72) received VB-111 in 4 treatment groups: subtherapeutic (VB-111 dose escalation), limited exposure (LE; VB-111 monotherapy until progression), primed combination (VB-111 monotherapy continued upon progression with combination of bevacizumab), and unprimed combination (upfront combination of VB-111 and bevacizumab). The primary endpoint was median overall survival (OS). Secondary endpoints were safety, overall response rate, and progression-free survival (PFS).ResultsVB-111 was well tolerated. The most common adverse event was transient mild-moderate fever. Median OS time was significantly longer in the primed combination group compared with both LE (414 vs 223 days; hazard ratio [HR], 0.48; P = 0.043) and unprimed combination (414 vs 141.5 days; HR, 0.24; P = 0.0056). Patients in the combination phase of the primed combination group had a median PFS time of 90 days compared with 60 in the LE group (HR, 0.36; P = 0.032), and 63 in the unprimed combination group (P = 0.72). Radiographic responders to VB-111 exhibited characteristic, expansive areas of necrosis in the areas of initial enhancing disease.ConclusionsPatients with rGBM who were primed with VB-111 monotherapy that continued after progression with the addition of bevacizumab showed significant survival and PFS advantage, as well as specific imaging characteristics related to VB-111 mechanism of action. These results warrant further assessment in a randomized controlled study

Introduction to A Compendium of Strategies to Prevent Healthcare-Associated Infections In Acute-Care Hospitals: 2022 Updates.

Since the initial publication of A Compendium of Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals in 2008, the prevention of healthcare-associated infections (HAIs) has continued to be a national priority. Progress in healthcare epidemiology, infection prevention, antimicrobial stewardship, and implementation science research has led to improvements in our understanding of effective strategies for HAI prevention. Despite these advances, HAIs continue to affect ∼1 of every 31 hospitalized patients, leading to substantial morbidity, mortality, and excess healthcare expenditures, and persistent gaps remain between what is recommended and what is practiced.The widespread impact of the coronavirus disease 2019 (COVID-19) pandemic on HAI outcomes in acute-care hospitals has further highlighted the essential role of infection prevention programs and the critical importance of prioritizing efforts that can be sustained even in the face of resource requirements from COVID-19 and future infectious diseases crises.The Compendium: 2022 Updates document provides acute-care hospitals with up-to-date, practical expert guidance to assist in prioritizing and implementing HAI prevention efforts. It is the product of a highly collaborative effort led by the Society for Healthcare Epidemiology of America (SHEA), the Infectious Disease Society of America (IDSA), the Association for Professionals in Infection Control and Epidemiology (APIC), the American Hospital Association (AHA), and The Joint Commission, with major contributions from representatives of organizations and societies with content expertise, including the Centers for Disease Control and Prevention (CDC), the Pediatric Infectious Disease Society (PIDS), the Society for Critical Care Medicine (SCCM), the Society for Hospital Medicine (SHM), the Surgical Infection Society (SIS), and others
